Nainital, the "Lake District of India," is a popular hill station in Uttarakhand located at \(\approx2,000\) meters in the Kumaon Himalayas, famous for the emerald Naini Lake, the Naina Devi Temple, and colonial heritage. It offers boating, trekking, and wildlife viewing at a high-altitude zoo. The area was established in 1841 after its "discovery" by British settlers, later becoming a summer retreat.
